Mecanismo genético da herança de resistência à Stemphylium solani e insensibilidade a sua fitotoxina em algodoeiro.
No full textA mancha preta do algodoeiro causada por Stemphylium solani ocorre em várias regiões produtora de algodão do Brasil, causando severos prejuízos em rendimento especialmente no Estado do Paraná (Mehta, 1998; Lima et al, 1997). O patógeno ataca apenas as folhas e as infecções de maçã e do colmo até agora não foram observadas. Recentemente, Mehta & Brogin (2000), reportaram que S. solani do algodoeiro produziu fitotoxina, ..
Nomenclature for continuous renal replacement therapies
No full textContinuous renal replacement therapies (CRRTs) have evolved over the last decade, but there is no standard terminology for the defferent methods in use, At an International Conference on CRRT, held in San Diego, CA, November 9-10, 1995, an international panel of experts developed a proposed nomenclature for these therapies, The nomenclature was developed to define common terms and to use a standardized language when papers in the field of CRRT are reviewed and published, This article describes the definition for each technique, It is hoped that these definitions will be used as a framework for subsequent descriptions of new techniques in the literature.

Acute dialysis quality initiative (ADQI)
No full textA new star is born. Its name is ADQI which stands for Acute Dialysis Quality Initiative. In the firmament of guidelines and directions for appropriate management of renal diseases, little has been done so far concerning acute renal failure and its treatment. For this reason we felt that a process seeking consensus and evidence-based statements in the field of acute renal failure was needed
The Acute Dialysis Quality Initiative: The New York Conference
No full textOver 300,000 Americans develop acute renal failure each year, and half die. In recent years, there have been considerable advances in our understanding and technical capabilities, but consensus over the optimal way to deliver care does not exist. Consequently, a conference held in New York in the year 2000 has given birth to the Acute Dialysis Quality Initiative (ADQI). The conference aimed at establishing an evidence-based appraisal and set of consensus recommendations to standardize care and direct further research on the application of continuous renal replacement therapy (CRRT). CRRT is being used at ever-increasing rates in the United States. Today, approximately one quarter of all patients with acute renal failure are treated with CRRT. Despite the increasing use, there are presently no published standards for the application of this therapy, and practice patterns vary widely between individual centers. Results from recent clinical trials on selection of dialysis membranes and dialysis dose provide strong, yet often conflicting, evidence to guide therapy. Other areas of uncertainty have not been sufficiently addressed by clinical studies and directives for future research are needed. Finally, the success of multicentered clinical trials in supportive care in the intensive care unit (transfusion thresholds and ventilator management) have intensified and renewed interest in the study of supportive care methods as a major target for future research. These developments have set the stage for the first ADQI conference; the final objectives are the development of evidence-based practice guidelines and directions for future research.

Blood purification in non-renal critical illness
No full textExtracorporeal therapies designed to remove substances from the circulation now include hemodialysis, hemofiltration, hemoadsorption, plasma filtration, cell-based therapies and combinations of any of the above. In recent years, there have been considerable advances in our understanding and technical capabilities, but consensus over the optimal way, and under what conditions to use these therapies does not exist. Consequently, we have initiated a series of conferences under the auspices of the Acute Dialysis Quality Initiative (ADQI). ADQI aims at establishing an evidence-based appraisal and set of consensus recommendations to standardize care and direct further research. The results of previous consensus conferences are available on-line at www.ADQI.net. ADQI conferences have focused on research and management of renal disease. However, extracorporeal therapies are being used or investigated in the management of many other disease processes including systemic inflammation, liver disease, cardiac disease and thrombotic diseases
Consensus development in acute renal failure: the Acute Dialysis Quality Initiative
No full textPurpose of review Although acute renal failure is both common and highly lethal in the intensive care unit, our understanding of the epidemiology and pathophysiology of acute renal failure is limited, and treatment for acute renal failure is extremely variable around the world. The general lack of consensus with regard to definitions, prevention, and treatment of acute renal failure has limited progress in this field. Recent findings Consensus in acute renal failure requires establishing a framework in which intensivists, nephrologists, pharmacologists, and others who care for critically ill patients with or at risk for acute renal failure can reach consensus and develop evidence-based practice guidelines. The Acute Dialysis Quality Initiative seeks to provide an objective, dispassionate distillation of the literature and description of the current state of practice of dialysis and related therapies as they are applied to acutely ill patients. The purposes of Acute Dialysis Quality Initiative are first, to develop a consensus of opinion, with evidence where possible, on best practice; and second, to articulate a research agenda to focus on important unanswered questions. Summary Broad consensus in the diagnosis and management of acute renal failure and in the use of blood purification in nonrenal critical illness is achieveable. Standardization of definitions, practice, and research methodology is urgently needed, and specific proposals have been made by an international, interdisciplinary group
